Description

Technical Field

[0001] The utility model belongs to the field of air-cooled module machines, and in particular relates to an anti-frost heat exchanger used for air-cooled module machines. Background Art

[0002] Air-cooled module units are based on modular technology and use air as the cold (hot) medium. As an integrated central air-conditioning equipment with both cold (heat) source and heat source, they are widely used in modern life. However, current air-cooled module units will encounter various problems in actual operation.

[0003] When the temperature on the fin surface is lower than 0℃, when the outdoor air has a certain humidity and when the unit is running, the water formed will frost on the fin surface. As time goes by, the frost will become thicker and thicker, and even extend from the bottom of the heat exchanger to the fan above, causing the evaporation temperature to become lower and lower, affecting the operation of the device.

[0004] In rainy and snowy weather in winter, when the outdoor temperature is below zero, a layer of white frost will form on the surface of the fins, blocking the air duct and affecting heat exchange. In addition, condensation water is generated during the operation of the unit, and the white frost will make the frosting more serious.

[0005] Manual defrosting is used in the prior art, but in order to prevent too much heat loss, the defrosting time is short, resulting in the phenomenon that the frost is not completely defrosted, and the disassembly and reassembly of the device requires a lot of manpower and time.

[0036] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0037] An anti-frost heat exchanger 1 for an air-cooled module machine comprises: a heat exchange plate 1, wherein two heat exchange plates 1 are provided, the two heat exchange plates 1 correspond to each other and are fixedly connected to a support frame 2; a support frame 2, wherein the support frame 2 is a hollow triangular structural member, and the two heat exchange plates 1 are fixedly connected to two sides of the support frame 2 respectively; a heating pipe is fixedly provided on the inner side of the support frame 2, and a drainage hole 201 corresponding to the heat exchange plate 1 is opened on the support frame 2; the two heat exchange plates 1 are arranged obliquely, and the angle between the two heat exchange plates 1 is an acute angle.

[0038] A heating pipe is provided on the inner side of the support frame 2. When the operating environment temperature is low, the heating pipe heats the device to prevent frost on the bottom of the coil. The angle between the heat exchange plates 1 is an acute angle so that condensed water can flow down quickly.

[0039] The heat exchange plate 1 is provided with a plurality of ventilation holes 101 , which are arranged along the thickness direction of the heat exchange plate 1 , and one end of the ventilation hole 101 located on the outside of the heat exchange plate 1 is higher than the other end located on the inside of the heat exchange plate 1 .

[0040] The downwardly slanted ventilation holes 101 are for the air to be heat exchanged coming from the bottom of the device, and can flow quickly to the other end of the heat exchange plate 1 under the guidance of the ventilation holes 101. The temperature of the air directly flowing in from the ventilation holes 101 is higher than the temperature of the air flowing in after heat exchange from the heat exchange plate 1. This causes convection of air with a temperature difference to form between the two heat exchange plates 1. At this time, the temperature environment and air flow between the two heat exchange plates 1 are unstable, and the conditions for frosting are not met.

[0041] A stabilizing plate 3 is fixedly disposed between the two heat exchange plates 1 , two side walls of the stabilizing plate 3 are fixedly connected to the two heat exchange plates 1 respectively, and a bottom of the stabilizing plate 3 is fixedly connected to the support frame 2 .

[0042] The end surface of the heat exchange plate 1 located on the outside is a wavy structure. The air flowing in from the bottom of the device is diverted under the influence of the wavy structure, so that the air to be heat exchanged can flow more evenly from one end of the heat exchange plate 1 to the other end, thereby avoiding a large amount of air flowing in from the lower half of the heat exchange plate 1, resulting in excessive air humidity in the lower half of the heat exchange plate 1, thereby avoiding frost.

[0043] The heat exchange plate 1 is provided with a plurality of heat conducting fins 4 on the inner end surface, one end of the heat conducting fins 4 is in contact with the support frame 2, and the heat of the heat conducting pipe is transferred to the heat conducting fins 4 through the support frame 2, thereby improving the anti-frost effect.

[0044] The support frame 2 is a structural member made of metal, and the heating tube is also a structural member made of metal. The heating tube fits the inner wall of the support frame 2 to better conduct heat.

[0045] The heat exchange plate 1 is also provided with a plurality of coil holes 102 . The coil holes 102 are arranged along the length direction of the heat exchange plate 1 . Heat exchange tubes are arranged in the coil holes 102 .

[0046] A plurality of end plates 103 are fixedly provided on the side wall of the heat exchange plate 1, and the plurality of end plates 103 are fixedly connected to each other, and a plurality of through holes corresponding to the coil holes 102 are opened on the end plates 103 located at both ends of the heat exchange plate 1; the end plates 103 are fixedly connected to the support frame 2, and the heat exchange plate 1 is fixedly connected to the support frame 2 through the end plates 103.

[0047] The coil holes 102 and the ventilation holes 101 are perpendicular to each other and are not connected to each other, thereby increasing the temperature difference between the air directly flowing in from the ventilation holes 101 and the air flowing in after heat exchange through the heat exchange plate 1 .

[0048] A gap is provided between the heat exchange plate 1 and the support frame 2, which can increase the air flow rate and improve the drainage efficiency.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
